Immediate Mortality of Atlantic Salmon (Salmo Salar) Smolts Resulting from Passage Through a Kaplan Turbine at Holyoke Dam, Massachusetts

摘要

Turbine mortality experiments on Atlantic salmon smolts were conducted using radiotelemetry at a 17 MW Kaplan turbine at Holyoke Dam, Holyoke, Massachusetts. Hatchery-reared salmon smolts, approximately 21 to 35 cm (TL), were tagged internally with 30 MHz radio transmitters. Experiments consisted of three groups of fish, i.e., Live Test Fish, Sacrificed Test Fish, and Live Control Fish. Immediately after each test, the movement patterns of all fish were monitored in the tailrace below Holyoke Dam. The distribution and behavior of Sacrificed Test Fish were used as a basis for determining extent of mortality of Live Test Fish and Control Fish. (ERA citation 08:050869)
